I think for what it offers, Cubase Pro is tremendous value for money. I started out on Cubase on the Atari, when DAW’s didn’t even exist and even back then, it was revolutionary. I’be been using midi sequencers and DAWS for over 25 years.
As mentioned, yes, there are alternatives - many that took the groundwork and research that Cubase laid and ran with it; despite that, having been a longtime Cubase, Logic and PT user, for the work I do Cubase comes out on top. None over the level of midi editing Cubase does, and there are a lot of more ‘hidden’ tools that put others to shame (the PLE for example), Pool management, media bay.
Yes, there are other DAWS that have certain functionalities that Cubase doesn’t have - Reaper has taken big strides on the audio side, and is very effdicient - but imho, the GUI is a mess, it has no media bay nor the more advanced media management Cubase has.
Logic - it’s only cheap because Apple knows you’ll need to buy a Mac to run it. Its midi features seemed to not have been touched for over a decade, whilst the Garage Band side of things keeps improving. It has some great internal synths, in part by Apple buying up developers. But as a DAW. I think Cubase still has the edge.
Anyway, you got to decide whether the feature set is worth it for the kind of stuff you want to do. It might not be right for you - but that doesn’t mean its not good value for money.
